DOOM Multiplayer flickering on Radeon R9 GPU and later when using TSSAA (8TX)

Vulkan
1

Hi there,

Here’s the scenario:
Patterns of white / green flashy dots randomly occur when looking around / walking in DOOM Multiplayer under Vulkan mode (the issue also appears in some of the intense battle scenes with large amount of lights, effects).

Bottom line: This issue was already solved three months ago since Vulkan 1.0.21 was introduced as part of Crimson 16.9.1 and newer, but now it was broken again in Vulkan 1.0.30 which came with the latest Crimson ReLive 16.12.1.

Temporary solution 1: Roll back to the stable Vulkan 1.0.21 and leave in-game AA settings unchanged
Temporary solution 2: Keep the latest Vulkan 1.0.30 and change the in-game AA method from ‘TSSAA (8TX)’ to any of the other settings (with the price of ~10 fps less during gameplay)

Are there any chances for another patch to be released in the near future?

Thanks!

You should troubleshoot to AMD support or on their forum. This forum is meant for Vulkan developers and Khronos’ announcements.

Did that already, thanks!

This is a forum maintained by the specification makers and so likely not a good place to report this.

Tell this to AMD: AMD Issue Reporting Form
and/or to DOOM support: https://help.bethesda.net/app/ask/p/704/pf/PC

BTW I think those were 1.0.26 despite installer saying 1.0.21. But the last number is “patch” version of the specification and not very important in of itself. The driver version is more important.

BTW2 I had to revert myself to 16.11.5 because of issue in DX11 game… there’s no shame in it. If the older drivers work better, then use them.

Already filled out a new report to AMD this weekend - thanks!

BTW The stable Vulkan driver version was 1.3.0 - the new / buggy one is 1.4.1.
